We studied radiation dose in mammography through 34-46 kv range using acryl phantom. The obtained results were as follows: 1. Incident radiation was maximum with high kvp and thin added filtration. 2. Transmitted radiation by acryl phantom and its thickness were in reciprocal relationship. 3. The acryl thickness to produce comparable film density with soft tissue of breast was 6 cm. 4. The X-ray exposure for comparable density radiographs increased mammographic film more than medical x-ray film and the amount of x-ray exposure was directly proportional to the added filtration of x-ray beam. 5. The surface dose of x-ray exposure needed to produce film density of 1.0 for 6cm acryl phantom was 1,084-1,575mR in mammographic film and 476-625 mR in medical x-ray film.

Objectives : The purpose of this study is to find out the effects of Chuna treatment on neck pain caused by traffic accidents. Methods : The 10 patients were divided into 2 groups, with Group A treated with Acupuncture and Chuna, while group B was treated with Acupuncture only. We measured the Visual Analog Scale(VAS), Pain Disability Index(PDI) and Pressure Pain Thresholds before and after treatment in each group. The statistical analysis was performed by using a Mann-Whitney U test and Wilcoxon signed rank test. Results : 1. Group A showed significant improvements in VAS, PDI and Pressure Pain Thresholds(p<0.05). 2. Group B was significantly improved in VAS(p<0.05). However, there was no statistical significance in PDI and Pressure Pain Thresholds(p>0.05). 3. There was no statistical significance between Group A and Group B before and after treatment. Conclusions : These results imply that Chuna treatment with Acupuncture would beeffective and useful on the neck pain caused by traffic accidents.

물발자국은 인간의 활동을 통해 소비되는 직접수와 간접수의 총사용량을 산정함으로써 지속가능한 물이용을 유도하기 위한 효과적 수단으로 활용되고 있다. 본 연구는 서울시의 물이용 관리와 관련한 계획들의 문제점 분석을 통해 물발자국의 도입가능성을 분석하고 장단기적인 측면에서 도입 및 활용방안을 제시하고자 하였다. 또한 서울시 25개 자치구를 대상으로 시뮬레이션을 통해 청색 및 회색 물발자국을 산정하고, 지역별 물발자국의 차이점 분석과 이를 바탕으로 물발자국을 줄이기 위한 대안들을 모색하였다. 물발자국 측면에서의 서울시 물환경시스템에 대한 분석은 크게 청색물발자국과 회색물발자국으로 나누어 수행하였다. 개인이나 공동체가 제품이나 서비스를 생산 소비하기 위해 필요한 지표수와 지하수의 양을 의미하는 청색물발자국을 분석하기 위해서 서울시의 각 행정구역별 지하수의 사용량과 생활용수의 사용량을 합산하여 추정하였다. 각 행정구역별 청색물발자국을 인구수와 세대수 비율로 확인해 본 결과 중구, 종로구 강남구, 용산구, 서초구 등의 순으로 높게 나타났다. 회색물발자국은 각 행정구역별 BOD기준의 오 폐수발생부하량을 배출기준 수질(BOD기준 3.5ppm)로 정화하여 배출할 때 사용되는 물의 양을 추론하여 산출하였다. 각 행정구역별 회색물발자국을 인구수와 세대수 비율로 확인해 본 결과 중구, 종로구 강남구, 용산구, 서초구, 영등포구 등의 순으로 높게 나타났다. 본 연구 결과는 물관리 있어 공급중심의 양적 관리 정책의 한계를 극복하기 위한 일환으로 물발자국의 개념 및 방법의 도입을 제안하였으며 이는 환경적 경제적 사회적으로 보다 탄력적이고 지속가능한 물관리 정책을 모색하는데 중요한 기초자료가 될 것으로 기대된다.

Objectives : This study was done to investigate the relativity of thermography to HRV(heart rate variability) in Sasang constitutional groups. Methods : We investigated 87 healthy workers consisted of 10 Taeumin, 47 Soeumin, 30 Soyangin. After diagnosing the Sasang constitution by QSCCII(Questionnaire for the Sasang Constitutional Classification), we ana lysed their HRV -time domain and frequency domain and also checked their thermography in April 2009. Results & Conclusions : Analysing the thermography, The whole skin temperature was showed equaly in many Taeumin, the face, Upper burner skin temperature was showed high in many Soeumin, and the abdomen skin temperature was showed low in many Soyangin. The relativity of the sympathetic index to skin temperature was high in Taeumin. The higher sympathetic index, the higher Upper burner skin temperature in Taeumin, the higer most of the skin temperature in Soyangin, lower the whole skin temperature in Soeumin.

To genetically breed powerful multifunctional antagonistic bacteria, the urease gene of alkalophilic Bacillus pasteurii was transferred into Bacillus subtilis YB-70 which had been selected as a powerful biocontrol agent against root-rotting fungus Fusarium solani. Urease gene was inserted into the HindIII site of pGB215-110 and designated pGU266. The plasmid pGU266 containing urease gene was introduced into the B. subtilis YB-70 by alkali cation transformation system and the urease gene was very stably expressed in the transformant of B. subtilis YB-70(pGU266). The optimal conditions for the transfomation were also evaluated. From the in vitro antibiosis tests against F. solani, the antifungal activity of B. subtilis YB-70 containing urease gene was much efficient than that of the non-transformed strain. Genetic improvement of B. subtilis YB-70 by transfer of urease gene for the efficient control seemed to be responsible for enhanced plant growth and biocontrol efficacy by combining its astibiotic action and ammonia producing ability.

Objectives : This study was performed to report the effect of Giungoroen-therapy based on song psychotherapy in the treatment resistant patient with psychosomatic disease. Methods : A 43 year-old female patient suffered from headache, facial numbness, right upper and lower limb's numbness, ptosis, chest discomfort, dysarthria without identifiable physical cause. We diagnosed her as psychosomatic disease, and tried to apply Giungoroen-therapy with Korean traditional medical treatment. But she was resistant to Giungoroen-therapy. So we applied Giungoroen-therapy based on song psychotherapy. Results : After the Giungoroen-therapy based on song psychotherapy, the patient revealed her unrecognized hidden issues and got some insights about herself. Then the symptoms, such as headache, facial numbness, right upper and lower limb's numbness, ptosis, chest discomfort and dysarthria were reduced considerably. Conclusions : These results suggest that Giungoroen-therapy based on song psychotherapy can be effective on improvement of resistant psychosomatic disease.

Pain disorder is a category of somatoform disorder that be diagnosed when the pain is starting and getting worse associated with psychological factors. At the recent study, it revealed that stress might be more strong factor in occurring and sustaining the somatoform disorder. In this case, a 42 years old female patient had a chronic pain disorder 3 years ago, suddenly complained of an eyeball pain due to retina rupture induced by severe stress. In the view of oriental medicine, pain disorder belongs to GuQiJakTongJung. So, we diagnosed her state as GuQiJakTongJung and treated her such as herbal medicine, acupuncture and phlebotomy therapy. In result, the chronic pain of the patient was improved, and also general condition was getting better.
